    Some atypical flutter characteristics of the NACA0015 profile

  • Original language description

    The part of the aeroelastic experiments with profile carried out in wind tunnel of the Institute of Thermomechanics, v.v at stream velocity M = 0.15-0.38 in the interval of Reynolds numbers Re = (1.8-5.0)105 is presented. The results relate to the self-excited vibration of the profile NACA0015, which had two degrees of freedom allowing rotation and transverse displacement of the profile. The elasticity of the two degrees of freedom support has not been, during the experiments, changed. The dependence of Strouhal numbers on the speed of the stream.has been obtained. In one case the excitation of an unstable state occured and during the measurement the jump to a stable state arised. The kinematics of the model during this transition is described.in detail.
